Skilling: Cooler temps coming but it’s not a ‘polar vortex’

The Chicago area is in for a drop in temps next week, which has some people flashing back to this past winter and using the “PV Word:” Polar Vortex.

Not so says WGN’s chief meteorologist Tom Skilling.

“Some are calling this a “polar vortex”-type pattern. There isn’t a polar vortex in summer. The polar vortex develops in the cold season in the planet’s arctic regions,” he says. “…The tendency toward cooler than normal temps here is similar though far less extreme than what we saw so frequently this past winter.”

Skilling’s forecast says the cooler air coming in to Chicago and the Midwest next week will generate 6-10 days of temperatures “well below normal.”
